The modular structure of the® digital and Promo® systems allows simple and fast replacement of the aerosol sensor within a model group.

Depending on the application, there are aerosol sensors available to the user for different concentration ranges from < 1 particle/cm3 up to 106 particles/cm3.

Aerosol sensors can also be supplied pressure-resistant up to 10 bar for isobaric or heatable up to 470°C for isothermal measurement conditions or made of special materials, e.g. Hasteloy, for chemically aggressive aerosols.

By means of the patented optical fibre technology, the aerosol sensors can be place directly at the measurement location to minimize sampling losses. They can be used at inaccessible measuring sites, the non-heatable sensors even in EX areas.

The robust and simple design ensures long service life, simple cleaning and therefore reliable and economic operation of the overall system, which can be calibrated by the customer on-site.
